Officer Jason Flanery reportedly crashed his patrol vehicle into a parked car and refused to take a breath alcohol test.

The St. Louis police officer involved in the shooting death of VonDerrit Myers Jr. in October 2014 has resigned amid a DUI probe, the St. Louis Post-Dispatchreports.

Police opened the probe after Officer Jason Flanery reportedly hit a parked car while driving his patrol vehicle early Saturday. Witnesses told police Flanery fled shortly after damaging the car. When officers arrived at his home, where the patrol car was also found, he refused to take a breath alcohol analysis test. Police obtained a search warrant and returned to the home to draw his blood.

“We handled the criminal investigation just as we would anyone in a suspected drunk-driving accident,” [St. Louis Police Chief Sam] Dotson said late Saturday evening.

“When he refused the breath alcohol test, we followed our procedures and obtained a search warrant to draw blood.”

Flanery was arrested and booked Saturday on suspicion of driving while intoxicated and misdemeanor leaving the scene of an accident.

He was released pending application for warrants.

Flanery received no special privileges, Susan Ryan, a spokeswoman for St. Louis Circuit Attorney Jennifer Joyce said.

Last year, Flanery was thrust into the media spotlight after the off-duty cop shot and killed 18-year-old Myers just two months after the fatal shooting of Michael Brown Jr. Flanery said the Shaw teenager fired multiple shots at him, prompting him to open fire. The police shooting sparked additional protests in the St. Louis neighborhood, heightening tension between the community and law enforcement.

In May, the circuit attorney’s office announced that Flanery would face no criminal charges in the shooting.

As of Monday morning, Flanery also does not face any charges stemming from the alleged DUI.
